FRIEDRICH, 0F HOLYOKE MASSACHUSETTS, ASSIGNOR TO THE CHENEY COMPANY, OF WINCHESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS METAL FLASHING Original No. 1,843,948 dated February 9, 1932, Serial No. 490,447, filed. October 22, 1930. Application for reissue filed April 15, 1932. Serial No. 605,540.

. 1 This invention relates toan lmprovement in metal flashings.

An object of my invention is to provide a flashing for forming a water-tight joint between the top or upper surface of a wall and the coping stone. In the flashing construction disclosed in my pending application, Serial No. 405,180, filed November ,6, 1929, there is shown," described and claimed a flashing having a longitudinally extendin rib or struck-up portion, which is central y located with reference to the opposite side edges of the flashing This rib is substantially wedge-shape in cross section. This construction permits the opposite side edgesgto be folded downward onto the inner and outer faces of a wall and suitably connected to metal coverings on these faces by means of a lock, or other joint construction.

My present invention also discloses the longitudinally extending rib construction of In my prior flashing construction,-thed wedge-shaped longitudinally extending rib, effectually permits-lateral movement of the coping. My present invention elfectually prevents the coping from movement in either a longitudinal or lateral direction, as will be described.

Referring to the drawing:

Fig. 1 is a perspective view showing the top or upper surface portion of a wall with the flashing in place and ablock of coping located thereon;

Fig. 2 is a plan view of the flashing removed, illustrating the struck-up and transversely arranged projections;

Fig. 3 is a sectional: view on the line 33 of Figg 2 showing two of the struck-up ribs; and v flashing.

ing S-shaped portions 5' which, it will be noted, extend in opposite directions (see Fig. 3), whereby the coping blocks 6 will be effectually prevented from longitudinal movements, since the mortar, cement, or other like adhesive material will fill the recesses 7 and 9 presenting an upwardly extending loop for the reception of mortar and the like. These struck-up portions advantageously may be substantially S-shape, as shown.

In use, the flashing is first placed on a layer of mortar 8 on the upper surface of thewall.

When the flashing is placed on the wall, it is retained in place by the side flanges 4 and mortar under the opposite S-shaped sides of the wedge-shaped rib 3. Next a layer of mortar 8 is laced on the upper surface of the is will enter and fill the recesses 7,'as well as the spaces 3 under the rib, 3. The block of coping6 is now put in lace on the mortar 8. Itis obvious that the lock of coping wil be eflectually prevented from both lateral and longitudinal movement, with reference-to the upper surface of the wall; the rib 3 preventing lateral movement, and the struck-up S-shaped portions 5 preventing longitudinal movement, after the mortar 8 has set. It will, therefore, be seen that I have provided a metal flashing plate that is simple and economical in construction and one that eflectually prevents a coping block from becoming dis laced.

It should also be state that the mortar 8, under the flashing plate, will enter the openings 9 and materially assist in preventin the longitudinal 'movement. of the flas ing: v

plate2.

What I claim is:

1'. A sheet of flashing comprising a metal plate having a longitudinally extending struck-up wedge-shaped rib with overhanging side edges and struck-up transversely extending ribs formed with overhanging porloop extendingupwardly from the plate.

4. As an article of manufacture, a flashing plate comprising a member having a plurality of transversely arranged projections above its upper surface, said projections being substantially S-shaped in cross section and a longitudinally extending struck-up rib substantially wedge-shape in cross section,

\ whereby when mortar is applied to the upper surface of the flashing and a coping block placed thereon the block will be prevented from both lateral and longitudinal movement, as described. I

' 5. A sheet of flashing composed of metal, as copper, and formed with S-shape struckup rib portions providing overlying recesses opening from said sheet on opposite sides thereof and at least one of said recesses terminating in a laterally extending section having substantially parallel sides in which a hardening material, as mortar or the like, engages for retaining coping block or the like in place.

6. A sheet metal flashing plate provided with a main ribbed portion formed in said plate and providing an undercut recess for the reception of mortar for locking said flash ing sheet to said mortar bed against move- I ment vertically and longitudinallyin one direction. and a plurality of spaced projections formed from said sheet and arranged to re ceive mortar for locking said flashing sheet against movement in another longitudinal direction.

7 A sheet of flashing comprising a metal plate having a primary struck-up rib with overhanging side edges and extending throughout a substantial portion of the sheet iii one direction, and a series of struck-up ribs extending in a transverse direction and formed with overhanging portions to provide recesses for receiving mortar or the like.

8. A sheet of flashingcomprising a metal plate deformed to provide spaced ribs exengagement with the mortar, the upper surstructures comprising a sheet of sheet metal of the width to extend substantially through the wall of said structure and thereby provide a means for deflecting and draining moisture of infiltration from said wall, said flashing being deformed to provide a series of struckup encased projections extending upwardly from the sheet providing recesses on oppo site sides of said sheet for the reception of mortar to bond the flashing sheet and masonry structure against relative movement in all directions.

10. A sheet metal flashing for masonry structures comprising a sheet of sheet metal of the width to extend substantially through the wall of said structure and thereby provide a means for deflecting and drawing moisture of infiltration from said wall, said flashing being deformed to provide a series of spaced interlocking means arranged in right angular relation to each other and each providing recesses on opposite sides of said sheet for the reception of mortar to bond the flashing sheet and masonry structure against relative movement in all directions.

11. A building structure comprising a series of superposed courses-of masonry interspaced by beds of mortar and the like. and a flashing imbedded in the mortar of one of said courses and comprising a metal sheet providing a means for intercepting moisture of infiltration into said masonry, said flashing sheet being deformed to provide spaced interlocking means arranged substantially at right angles to each other for receiving the mortar and bonding the flashing sheet and masonry against relatively shifting in all directions.

1 2. As an article of manufacture, a metal flashing sheet for masonry walls, said sheet being of substantial width to extend from side to side of said wall. and formed with a like.

13. As an article of manufacture, a metal flashing sheet for masonry walls, said sheet being formed with a longitudinal series of transversely extending ribs having reversely bent recesses forming seats for interlocking face of one recess inclining downwardly toward the plane of said sheet.

14. As an article of manufacture, a metal flashing sheet for masonry walls, said sheet being of substantial width to extend from side to side of said wall and thereby provide means for deflecting and draining moisture of infiltration from said wall, said flashing sheet being, deformed to provide means for permanent y bonding thefiashing sheet and wall together against movement in all directions including a plurality of groups of struck-up projections, the projections of each group being unsymmetrically disposed with relation to each other, and each providing recesses for the reception of mortar which, upon hardening, will serve to revent relative lateral and longitudinal shifting of the sheet with reference'to the masonry wall.
